A high demand for super fruit and nutraceuticals derived from these fruits has appeared in the market to address the need for products with high antioxidant contents. <i>Aronia mitschurinii</i> is a fruit which can satisfy the demand for one of highest known antioxidants content and low sugars. Research has been completed since 2006 studying the cultural management of aronia and antioxidant content per harvest, however in-depth phytochemical analysis over the ripening period has yet to be performed. The need for in-depth study of ripening arises from preliminary data for aronia that clearly shows peaks for both anthocyanins and soluble sugars, yet these two peaks may be up to 2-3 weeks apart, while the visual color of the berries is the same. It is important to harvest on the peak of anthocyanins for pharmaceutical needs, while for food production the harvesting should happen on the peak of brix. This project has two fundamental goals: (1) observe the ripening of aronia and find both laboratory and in-field methods to determine the optimal harvesting time; and (2) compare the data for four berries with almost same (and much higher than other known fruits) content of anthocyanins, to determine if they have the same or different ripeness patterns. The results for total content of anthocyanins, flavonoids, polyphenols tannins, and brix over the ripening period for aronia, elderberries, mulberries and hascaps is presented, along with phytochemical screening of juice from the berries.
